"We have been conducting searches at Amnesty's office in Bengaluru and its Director's (Aakar Patel) home since this afternoon," IANS quoted an ED source as saying.

"We will release more information once the search ends," the source added.

Earlier this month, the ED had stopped operations of Greenpeace India Society’s 12 accounts with different banks and three current accounts of a private company pending an ongoing probe into suspected foreign exchange rule violations.
